ENVIRONMENTAL AND SAFETY CONCERNS
NWRT-91 is environmentally friendly, water-based, non-flammable and complies with VOC and other appropriate government safety standards, legislation and regulatory requirements. Spatter or spills can be easily cleaned with water.
APPLICATION
Verify that walls, masonry, concrete, stucco, block (split faced/fluted) and mortar that have been treated with any form of chemical/acid wash are neutralized.
Verify that masonry, concrete, stucco, block (split faced/fluted) and mortar units in existing building are structurally sound and fully intact.
Before application, ascertain that the masonry walls have a neutral ph level.
Alkali or efflorescence should be treated with proper neutralizing compounds as recommended by masonry supplier before application can begin.
Application of NWRT-91 is possible in temperatures of 30° F to 110° F; Masonry surfaces ideally should be dry before work begins.

DUB'L LOOP-LOK™
Reinforcement System
100% protection against separation of wire tie from reinforcement.
Allows in-plane vertical and horizontal movement of masonry wythes while restraining tension and compression.
Loops welded shut to maintain allowable tolerance and system integrity.
Unlike horizontal eyelets, vertical loops will not clog with mortar as construction progresses.
Loop extends one direction only to allow simple placement of insulation. Slip on Loop-Lok™ Washer to mechanically lock insulation in place.

MIGHTY-LOK™
High Strength
Large diameter eyelets and pintles afford usage where high strength requirements are present and standard eyelets and pintles would fail (including extra-wide cavity conditions). Also designed for usage where standard eyelets and pintles would fail due to greater than normal misalignment of mortar joints between the 2 wythes.
Rounded eyelets engage pintles snugly in conformance with existing codes (less than 1/16" mechanical play). No oblong-shaped eyelets as found on other systems.
Available Truss style (#170-ML) or Ladder style (#270-ML).
